Abstract

miniBELEN-10A is a modular and transportable moderated neutron counter with a nearly flat detection efficiency up to 8 MeV. The detector was designed to carry out measurements of (α, n) reactions in the context of the Measurement of Alpha Neutron Yields (MANY) project. In this work we present the results of the commissioning of miniBELEN-10A using the relatively well-known thick-target neutron yields from 27Al(α, n)30P.

Abstract

Half-lifes (T1/2) of exotic neutron-rich isotopes of Ba, La, Ce, Pr, and Nd were measured at the RIKEN Nishina Center. The experimental setup consisted of the BigRIPS in-flight separator for ion selection identification, the Advance Implantation Detector Array (AIDA) for ions and β detection, and the BRIKEN detector for neutron counting. Using this setup, 4 new T1/2 have been measured for the first time, and 38 T1/2 have been remeasured with improved precision in several cases. These new experimental data should help to constrain theoretical models for calculations of T1/2. The status of the experimental analysis and preliminary results are provided in this contribution.

Abstract

miniBELEN is a modular and transportable neutron moderated counter with a nearly flat neutron detection efficiency up to 10 MeV. Modularity implies that the moderator can be reassembled in different ways in order to obtain different types of response. The detector has been developed in the context of the Measurement of Alpha Neutron Yields (MANY) collaboration, which is a scientific effort aiming to carry out measurements of (𝛼, 𝑛) production yields, reaction cross-sections and neutron energy spectra. In this work we present and discuss several configurations of the miniBELEN detector. The experimental validation of the efficiency calculations using 252Cf sources and the measurement of the 27Al(𝛼, 𝑛) 30P reaction is also presented.

Abstract

At the RIKEN Nishina Center, exotic neutron-rich isotopes of Ba, La, Ce, Pr, and Nd were measured. This work reports their half-lives (T1/2) and β-delayed neutron-emission probabilities (Pxn). The setup consisted of the BigRIPS in-flight separator for particle identification, the Advanced Implantation Detector Array (AIDA) for ions and β detection, and the BRIKEN neutron counter for neutron detection. Using this arrangement, 4 new T1/2 and 14 new P1n were measured. Furthermore, 38 T1/2 and 2 P1n values were remeasured, decreasing the uncertainties for some of them. In addition to improving predictions of nucleosynthesis models that describe the production of the rare-earth peak at A ∼ 160 via the r-process, these additional experimental data should help to constrain theoretical models for calculations of T1/2 and Pxn in this region.

Abstract

In this work, we present the design of a new modular and transportable neutron detector for ({\alpha},n) reactions. The detector is based on the use of several 3He-filled proportional counters embedded in high density polyethylene. In order to provide the detector with a response independent of the neutron energy, a flat response, an innovative design methodology has been applied. The method is based on the optimization of the counters contribution to the total efficiency by using thermal neutron absorbers. This allows to obtain flat responses up to 10 MeV. The characterization of a proof-of-concept prototype detector is presented. The perspectives for using this new detector for ({\alpha},n) reactions measurements are discussed., Comment: Proceedings del XXII Simposio Chileno de Fisica, 2020, submitted ato Journal of Physics: Conference Series

Abstract

We report results on the long-term variation of the neutron counting rate at the Canfranc Underground Laboratory, of importance for several low-background experiments installed there, including rare-event searches. The measurement campaign was performed employing the High Efficiency Neutron Spectrometry Array (HENSA) mounted in Hall A and lasted 412 live days. The present study is the first long-term measurement of the neutron rate with sensitivity over a wide range of neutron energies (from thermal up to 0.1 GeV and beyond) performed in any underground laboratory so far. Data on the environmental variables inside the experimental hall (radon concentration, air temperature, air pressure and humidity) were also acquired during all the measurement campaign. We have investigated for the first time the evolution of the neutron rate for different energies of the neutrons and its correlation with the ambient variables., Comment: 12 pages, 5 figures, 2 tables

Abstract

Beta-delayed neutron emission plays a fundamental role in the explosive nucleosynthesis of elements heavier than iron by the rapid neutron capture (r-process). The most ambitious project related to beta-delayed neutron detection of very exotic nuclei is carried out by the BRIKEN collaboration at RIKEN Nishima Center. In this work, a brief description of the BRIKEN project is presented. A methodology for the precise characterization of the BRIKEN neutron counter efficiency, for fast neutrons, using an uncalibrated 252Cf neutron source is described. The method relies on the well-known neutron multiplicity distribution of such source and correlation counting method. A detailed experimental study with the BRIKEN neutron counter and a 252 Cf neutron source at the RIKEN Nishina center is presented. The result of this work is the determination of the neutron detection efficiency of the BRIKEN neutron counter with high accuracy., Comment: Proceedings del XXII Simposio Chileno de Fisica, 2020, submitted ato Journal of Physics: Conference Series

Abstract

We have performed a long-term measurement of the neutron flux with the High Efficiency Neutron Spectrometry Array HENSA in the Hall A of the Canfranc Underground Laboratory. The Hall A measurement campaign lasted from October 2019 to March 2021, demonstrating an excellent stability of the HENSA setup. Preliminary results on the neutron flux from this campaign are presented for the first time. In Phase 1 (113 live days) a total neutron flux of 1.66(2) $\times$10$^{-5}$ cm$^{-2}$ s$^{-1}$ is obtained. Our results are in good agreement with those from our previous shorter measurement where a reduced experimental setup was employed., Comment: Proceedings of the 17th International Conference on Topics in Astroparticle and Underground Physics (TAUP 2021)

Abstract

The DEcay SPECtroscopy (DESPEC) setup for nuclear structure investigations was developed and commissioned at GSI, Germany in preparation for a full campaign of experiments at the FRS and Super-FRS. In this paper, we report on the first employment of the setup in the hybrid configuration with the AIDA implanter coupled to the FATIMA LaBr3(Ce) fast-timing array, and high-purity germanium detectors. Initial results are shown from the first experiments carried out with the setup. An overview of the setup and function is discussed, including technical advancements along the path. © 2022 Elsevier B.V.

Abstract

In this work, we present the design of a new modular and transportable neutron detector for (α,n) reactions. The detector is based on the use of several 3He-filled proportional counters embedded in high density polyethylene. In order to provide the detector with a response independent of the neutron energy, a flat response, an innovative design methodology has been applied. The method is based on the optimization of the counters contribution to the total efficiency by using thermal neutron absorbers. This allows to obtain flat responses up to 10 MeV. The characterization of a proof-of-concept prototype detector is presented. The perspectives for using this new detector for (α,n) reactions measurements are discussed., Proceedings del XXII Simposio Chileno de Fisica, 2020, submitted ato Journal of Physics: Conference Series
